“I've never written a fiction before about real people. . . . I read everything that I could find by people who met them and tried to get some impression of them, but as always when you write fiction, even if you have completely fictitious characters, you start by thinking of what is plausible, what would they say, what would they be likely to do, what would they be likely to think. At some point, if it is every going to come to life, the characters seem to take over and start speaking themselves, and it happened with [COPENHAGEN].”
